i strongly support this suggestion. actually, i suggest the same for
dealing with references (IORef/MVar/...), for example:
do x <- newIORef 0
y <- newIORef 0
z <- newIORef 0
z := *x + *y -- translated to { x' <- readIORef x; y' <- readIORef y;
writeIORef z (x'+y') }
Right, I realize my suggestion is the same as Ben's. I just prefer a
more succinct notation, like special brackets instead of a keyword. I
like your idea about IORefs. I think it should work as well for
STRefs... perhaps it needs to belong to a type class, in a way?
